Testcase: - turn StyledText widget's word wrap on in a simple editor - open a file with 30 lines (for example), where two of the line are very long - line number ruler shows 1 - 30, but text widget has 32 lines
SWT.WRAP is currently not supported. See also bug 47280
Even SWT.WRAP is not going to be supported, could be fixed with: --- LineNumberRulerColumn.java Fri Oct 20 07:25:18 2006 +++ LineNumberRulerColumn_Fixed.java Tue Feb 27 21:25:30 2007 @@ -659,7 +657,9 @@ if (widgetLine == -1) continue; - int lineHeight= fCachedTextWidget.getLineHeight(fCachedTextWidget.getOffsetAtLine(widgetLine)); + // FIXED: For wrapped text widgets + int lineHeight= fCachedTextWidget.getLinePixel(widgetLine+1) - fCachedTextWidget.getLinePixel(widgetLine);
In our case this issue causes scrolling problems in an editor using the StyledText widget with SWT.WRAP. If the text is wrapped and you try to get to the next row by pressing "arrow down" (when the cursor is at the beginning of the line) this does not work. There are also some drawing problems which seem to occur when rich text is wrapped and such wrapped lines are deleted. To reproduce this issue, paste a text that exceeds the total height of the widget and has long lines that are wrapped in the editor. If some lines are deleted then and you scroll down using the scroll bar you get some strange display errors like in the attached screenshot.
